GRAW-BINDER.

SPECIFICATION forming part of Letters Patent No. 252,236, dated January 10, 1882.

Application filed J anuary 19, 1881*. (No model.) y

To y all 'whom it may concern Beit known that I, JOSEPH M. McMAs'rEa, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Grain-Binders; and I do hereby declare that the following is a full, clear, and exact description of the same, referencebein g had to the accompanyiugdrawings, in which Figure lis a top view ofa mechanism, showingmy invention. Fig. 2 is a bot-tom view of the same. Fig. 3 is a side elevation. Fig. et is a cross-section in line me of Fig. l. Figs. 5, 6, 7, 8, 9, and l0 are detail views.

My improvement relates to wire binders, and is designed to he used on a level with the harvester-platform, so that the grain does not have to -be elevated, as it' does in most grainbinders.

The inventionconsists in the construction and arrangement of parts, hereinafter morel V y ings'gg on the Aunder side of the body-plate, In the drawings, A represents a platform or denitely described and claimed.

table connected with the ordinary grain-plat-` form, and to which the mechanism that operates the binder is attached.

B is a thin plate of steel, which I denominate thebod`yplate,7 forming a part of the` platform. It has an extension of sheet-iron, of the same widthand thickness, which extends back from the attachment of the mechanism. On theunder side of the body-plate are two or more studs, ad, riveted to the plate and forming the bearings for a shaft, C, which turns freely therein, being operated by a pulleyT or gear-wheel, b, at one end, which receives motion from the harvester by any suitable means. To this shaft are secured, by keys or other suitable means, six'cams (marked respectively 1, 2, 3,4, 5, and 6,) by which meansthe several operating parts of the binder are actuated.

C G C are Ways in the `binder-platform, which extend longitudinally, and in which the standards of the compressor run. These waysmay :each be formed in one piece by suitable rolling', or be made in separate pieces riveted* or therwisesuitably secured together.` They have T-shaped slots, in which the corresponding T-shaped feet of the compressors run, thereby preventing the compressors from rising out of place.

D D D are the standards forming the compressor, the same having feet resting in the grooves or slots justdescribed. The feet are elongated longitudinally Vto produce a tirm bearing.

E is a rock-shaft connecting the tops of the standards.

c is a small cranlearm connecting rock-shaft E with a connecting-arm, F, which extends backward, andis pivoted at the opposite end to the top of a rock-arm, G. The latter is pivoted at its bottom to a stationary bearing, d, attachedl to the top of the body-plate. As the rock-arm G is turned forward and back upon its pivot, it will be seen that the compressors will he made to traverse forward and hack the length of the platform, thereby gathering one layer of grain into a bundle and returning for another:

H is a curved steel binder-arm, which is attached to a roller,f, journaled between bear- I, over the friction-wheels l1. h, thence down between the grooved wheels j j andi outside the bottom one, as'shown in Fig. 3, and is connected at its lower end with the end of the lower wire." `The reel I rests in aframeor bearing, J, and any desired amount of friction is applied upon the reel by means of a nut, l, which screws upon its shaft outside thebe'a'ring. By the means above described the desired amount of tension is produced in the wire to keep it taut. The binder-arm H,'where it passes the rock-arm G, restsbetween stops m ni, attached to arm G, and located. at some 4distance apart. The binderarm by striking these stops in its opposite motions limparts the forward and back motions to the rock-arm, and consequently to the compressors, thereby gathering the grain. Sufficient-space, however, is left between the stops m m for the binder-arm to pass down audhold the bundle It also IOO under tension before the pressure of the compressor is released.

rlhe rollerf has two pins, a a, provided with friction-rollers projecting from its sides, and the two cams l 2 are arranged upon the shaft C in opposition to each other, so that the tirst cam will strike its pin and turn-the roller sufficiently to throw the binder arm its full stroke in one direction, and will then release, and the second cam will then strike the other pin and turn the roller sufficiently in the other direction to throw the binder-arm its full stroke the opposite way, this reverse motion being productd by the cams by a constant forward revolution of the main shaft. The reverse position of the two cams on the shaft is illustrated most clearly in the crosssection Fig. 5.-

K is a reel on the underside of the body-plate, containing wire which passes beneath the bodyplate to the slot 7c, where it is connected with the upper wire by twisting, as will presently be described.

The twisting arrangement is shown in Figs. 6, 7, 8, and 9.

L is a vertical pinion, havingits bearings in a suitable support on the under side of the body-plate in line with and near the slot lr. An opening is made in the pinion on one side to admit the wire, and at the top ofthe pinion this opening is contracted to a narrow slot, o, which allows the entrance of a single strand of wire, but prevents the passage of two abreast. The frame or plates which support the pinion are also slotted, as shown at e, to admit the wire.

M is a rock-bar, pivoted at p, and having on its front end a segment-gear, q, which engages with the pinion L, and in its sweep revolves the pinion several times around to twist the wire. The bar M is operated by the two cams 3 and 4, which are set in opposition to each other on the main shaftin the same manner as Nos. l and 2, andxwhieh, by striking the baron opposite sides of its pivot, give itthe necessary rocking motion. v

N is a short vertical shaft, set on one side of and but a little distance from the pinion L. On top and bottom of this shaft are two plates, l? and R, which turn with the shaft. Each of these plates isprovided with ahookmr, which,

when the plates are turned inward to the full` extent, catch and hold the wires'in the slot of the pinion while the latter twists them. The upper plate has a square edge, s, which, when the plate is turned outward to its full extent, lies across the slot of the pinion in front of the same and prevents the wire entering the pinion. It also serves as a cutter to cut the wire after the twisting has been done, in which case the plate moves from its innermost position backward or outward, and the cutter s cuts backward across the top of the pinion or the plate in which it rests as a shear. The hook r/ on the lower plate, R, coincides with that on the upper one, but when thrown fully in it clamps the lower length of wire up against a fixed stop, z, as a pincher, and holds it fast in place while the twisting is done. By this means the twist of the wires cannot extend below the stop z, and this short twist is just sufticient to fasten the two wires together ready for a new bundle.

It should be noticed here that when the grain is drawn up by the comprgssor into a body, the curved arm H will be raised above the bodyplate such a distance that the grain will be brought against the wire which extends from the end of said curved arm down through the slot It', and the further movement of the compressor will bend the wire in and carry it with the grain, and when, finally, thelbinder-arm descends again the wire will be carried over and outside the bundle, and the double endsof the wire will be carried into the slot of the pinion and there twisted. When the cut of the wire is made the twist is severed in the center, the upper part being part of the wire binding the bundle and the lower part vbeing the joining ends ofthe upper and lower wires. Fig. l0 shows the wires twisted, but not cut. The cut would be made in the central untwisted part, which is the part that rests in the narrow upper end of the slot in the pinion.

On the lower end of the short shaft N is a roller, T, from the opposite sides of which project two pins, a u, havingfriction-rollers against vwhich strike the cams 5 and 6, set in opposition on the main shaft in the manner before described, and which act to rock the shaft forward and back. 1

S is a short shaft, resting in a socket on the under side of the body-plate and passing through the body-plate, having on its upper end, above the body-plate, an arm, V, which swings forward and back across the body-plate as the shaft is turned.

On the outer end of the arm are prongs w w. When the arm swings back over the bodyplate it slides under the bundle, and inl moving in the opposite way it catches the bundle IOO IOS

and throws it oif from the machine upon the ground.

On the lower end of shaft S are two pins, x

w, provided with friction-rollers, and these are acted upon to produce the rocking motion of the shaft by the two cams 3 and 4, set in opposition to each other on the main shaft,las before described. t

To the rock-shaftE are attached two or more long rods, y y, which extend longitudinally over the platform and press down upon the grain as it is gathered up by the compressor, thereby keeping it in place. They are raised in the back motion of the compressor by means of crank c. A

ItWill be noticed in this machine that but avsingle main shaft is used, and that all the cams a-re located upon this shaft, and that no gears are employed except the segment-gear andpinion by which the twisting is done'. lIn ordinary grain-binders complicated gearing is employed to produce the necessary motions of the different parts. Furthermore, here the cams are placed in opposition or reversely, so as to produce a rocking motion of the parts upon which they act, and in acting upon the pins the cams strike substantially atrght angies, as shown in Fig. 5, so that but little friction is produced.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. In a grain-binder, the combination of the reverse cams 5 and 6, set on the main shaft, the short upright shaft provided with pins u u, upon which the cams act, and the plates P R, attached to the shaft and provided with hooks for carrying the wires into the slotof the twisting pinion, as herrin shown and described.

2. In a grain-binder, the combination ofthe reverse cams l 2,the rollerf, armed with pins n n, upon whichthe cams act, the curved binder-arm H, attached to the roller, and the com- A pressor consisting ofthe standards D D, running in ways and connected by the crank c-and arms F G with the binder-arm, so as to be operated by the latter, as herein shown and described.

3. In a grain-binder, the combination of the short vertical shaft S, provided with pins :v x,

the cams 3 and 4, set on the main shaft, and the arm V, attached to the shaft S on top the body-plate, and provided with the prongs 'w w, as shown and described, and for the purpose specified.

4. ln a grain-binder, the combination ofthe curved binder-arm H, the rock-arm G, provided with stops m m, located at some distance apart, between which the binder-arm plays, the connecting-arm F, the crank-arm c, rock-shaft E, and standardsD D, as shown and described, and for the purpose specified..

5. AIn a grain-binder, the combination, with the short vertical shaft N, provided with a plate, P, at its top, having a hook, r, for drawing the wire into the slot of the twisting-pinion, of an auxiliary plate, R, at its bottom provided with a hook, r', which strikes a stop, z, and pinches the wire,l thereby limiting the downward twist of the wires, as herein shown and described.

In testimony whereofI have hereunto signed my name in the presence of two subscribing witnesses.
